Project Management with SAP R/3
Method by which a number of projects are summarized and analyzed under one or more generic terms.
In this way, you can, for example, summarize the costs of all the projects which belong to a controlling area or business area, and analyze them in the project information system.
The data is summarized using hierarchy structures, which you can define in the Project System implementation guide. The Project System uses the SAP classification system for this purpose.
You use characteristics to define the individual hierarchy levels in the summarization hierarchy.
